High-temperature thermal protection is a serious issue in developing reusable launch vehicle and hypersonic vehicle. Metallic thermal protection system and regenerative cooling technology are important parts of the thermal protection technology. Therefore, it is valuable to study their thermal performance and thermal design method.In this thesis, the theoretical analysis and numerical simulation was carried out about the heat transfer characteristics of the metallic honeycomb sandwich panel under aerodynamic heating and the thermal design method of regenerative cooling channel which was heated by hot gas. The main contents are as follows:A two-dimensional coupled heat transfer numerical model of metallic honeycomb sandwich panel was developed with the finite volume method and Monte Carlo Method, and the computer code was written. Then, by numerical calculation, the temperature distribution and equivalent thermal conductivity were obtained, the heat transfer mechanism was analyzed under various conditions, and the effect of geometric parameters, thermal properties, and other factors was investigated.Based on the theory of heat conduction under the convection coupled with radiation boundary conditions, the coupled heat transfer model of regenerative cooling channel was established with the finite volume method, the Monte Carlo Method and forced convection correlation, and the computer code was also written. Then, the applicability of four kinds of typical forced convection correlations was analyzed by numerical simulation, and the effect of radiative heat transfer within regenerative cooling channel was discussed under various conditions.By analyzing the heat transfer process of regenerative cooling panel, the structure thermal design model of regenerative cooling channel was established. Then, an auto-adaptive algorithm for the structure thermal design of regenerative cooling panel was suggested, which is based on heat flux distribution of the hot gas-side and temperature control boundary, and the computer code was developed. It proves the feasibility of the algorithm by numerical simulation of some typical case.Through the investigation in this thesis, a more in-depth understanding was obtained about the heat transfer characteristics of the metallic honeycomb sandwich panel and regenerative cooling channel, and it provides a valuable reference and an optional thermal design method for the application of metallic thermal protection technology.
